Hydromorphone injection may be habit forming, especially with prolonged use, and cause slowed or stopped breathing or death if it is overused. Inject hydromorphone injection exactly as directed. Do not use more of it or use it more often than prescribed by your doctor, While using hydromorphone injection, discuss with your health care provider your pain treatment goals, length of treatment, and other ways to manage your pain. Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications, or if you have or have ever had depression or another mental illness. There is a greater risk that you will overuse hydromorphone if you have or have ever had any of these conditions. Talk to your health care provider immediately and ask for guidance if you think that you have an opioid addiction or call the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) National Helpline at 1-800-662-HELP.
Hydromorphone injection is available as a regular strength solution (Dilaudid) and a concentrated solution (Dilaudid-HP) that contains more hydromorphone in each milliliter of solution. Your doctor should only prescribe the concentrated solution if you are opioid tolerant (have been treated with certain doses of narcotic medications for at least 1 week, allowing your body to adjust to this type of medication). The concentrated solution may cause serious side effects or death if it is used by a person who is not opioid tolerant. Be sure that you know which hydromorphone solution your doctor has prescribed, and always check to be sure you are receiving the correct medication.
Do not allow anyone else to use your medication. Store hydromorphone injection in a safe place so that no one else can use it accidentally or on purpose. Keep track of how much medication is left so you will know if any is missing.

Tell your doctor if you are taking or plan to take any of the following medications: benzodiazepines such as alprazolam (Xanax), chlordiazepoxide (Librium, in Librax), clonazepam (Klonopin), diazepam (Diastat, Valium), estazolam, flurazepam, lorazepam (Ativan), oxazepam, temazepam (Restoril), and triazolam (Halcion); medications for mental illness or nausea; muscle relaxants; other narcotic pain medications; sedatives; sleeping pills; or tranquilizers. Your doctor may need to change the doses of your medications and will monitor you carefully. If you use hydromorphone injection with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own.
Drinking alcohol, taking prescription or nonprescription medications that contain alcohol, or using street drugs during your treatment with hydromorphone injection increases the risk that you will experience serious, life-threatening side effects.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
In case of emergency/overdose
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
While you are using hydromorphone, you may be told to always have a rescue medication called naloxone available (e.g., home, office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opiates to relieve dangerous symptoms caused by high levels of opiates in the blood. You will probably be unable to treat yourself if you experience an opiate overdose. You should make sure that your family members, caregivers, or the people who spend time with you know how to tell if you are experiencing an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer's website to get the instructions. If someone sees that you are experiencing symptoms of an overdose, he or she should give you your first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. Your symptoms may return within a few minutes after you receive naloxone. If your symptoms return, the person should give you another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.
Symptoms of overdose may include the following:
- slowed or stopped breathing
- coma (loss of consciousness for a period of time)
- muscle weakness
- cold, clammy skin
- narrowing or widening of the pupils (dark circle in the middle of the eye)
- slowed or stopped heartbeat
What other information should I know?
Keep all appointments with your doctor.
This prescription is not refillable. If you continue to have pain after you finish the hydromorphone injection, call your doctor.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
